SC16IS7xxRK hardware SPI and I2C hardware UART library

Firmware Libraries
1

This library supports the SC16IS740, SC16IS750, SC16IS760 single UART and SC16IS752, SC16IS762 dual hardware UART chips. Additionally you can add multiple chips to a single SPI or I2C bus for even more ports. This is a great way to add additional hardware UARTs, especially to nRF52 devices which only have a single available UART.

The new library fixes several design limitations of the SC16IS740RK library:

  • Support for dual-port chips
  • Buffered read mode uses threads and buffer of user-defined size to prevent FIFO overflow
  • Hardware flow control support
  • IRQ support (though see documentation as it's not as useful as you'd think)
